Yomi no Tsugai (Japanese: 黄泉のツガイ, RR: Yomi no Tsugai)—translated as The Daemons of the Shadow Realm—is a Japanese manga series written and illustrated by the legendary Hiromu Arakawa, the creator of Fullmetal Alchemist. Since its debut, it has garnered significant interest in Indonesia, particularly among veteran manga readers who appreciate Arakawa’s signature blend of dark mystery, unique power systems, and tight storytelling.

The story follows Yuru, a young boy who lives a secluded, primitive life in a remote mountain village, where he and his twin sister, Asa, are treated with great reverence. His peaceful life is shattered when modern-day soldiers with advanced technology and mysterious supernatural creatures attack the village. Yuru soon discovers that the "Asa" he knew was a fake, and his real sister is actually leading the raid. Amidst the chaos, Yuru awakens his status as the master of the "Tsugai" (Daemons)—powerful, paired supernatural entities—and must venture into the modern world to uncover the dark truth behind his bloodline and his village's secrets.
